SAFETY-RAZOR.

Application filed August 28, 1913.

' To all whom it may camera:

Be it known that I, JAMES J. FITZGERALD, a subject of the King ofEngland, residing at Pittsburgh, in the' county-of Allegheny and Stateof Pennsylvania, have. invented certain new and useful Improvements inSafety-Razors, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to safety razors, and the object thereof, is toprovide, in a manner as hereinafter set forth, a safety razor having atriangular-shaped blade presenting three cutting edges, any one of whichcan be used, and to further provide the handle of the razor with means,in a manner as hereinafter set forth,- for indicating what cutting edgeof the razor blade has been used.

A further object of the invention is to provide, in a manner ashereinafter set forth, a safety razor, having attached to the holder thehandle and further having means for fixedly maintaining the guard andblade clamped to the holder so that the blade will be maintained inposition for use.

Further objects of the invention are to provide a safety razorconsisting of com paratively few parts, convenient and efiicient in itsuse, inexpensive to manufacture, easily assembled, strong and durable.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arran ement of parts ashereinafter more specifically described and illustrated in theaccompanying drawing, wherein is shown an embodiment of the invention,but it is to be understood Specification of Letters Eatent.

that changes, variations and modifications can be resorted to which comewithin the scope of the claims hereunto appended.

In the drawing wherein like reference characters denote correspondingparts throughout the several views Figure 1 is an elevation of a safetyrazor in accordance with this invention,

Fig. 2 is a sectional elevation, broken away,

Fig. 3 is a detail in plan, broken away,

Fig. at is a top plan view of the razor,

. Fig. 5 is an inverted plan of the guard and handle,

Fig. 6 is a plan of the guard,

Fig. 7 is an inverted plan of the holder,

Fig. 8 is a plan of the blade.

Serial No. 787,223.

Referring to the drawing 16 denotes a triangular shaped holder havingformed integral with its inner face a substantially oval-shaped boss 17.The reference character 18 denotes the handle, the latter having oneterminus provided with peripheral threads, as at 19 and said threadedterminal 19 is formed integral with the boss 17 The reference character20 denotes the blade, which is triangular in contour, thereby pro vidingthe cutting edges 21, 22 and 23, the edge 21 indicated as at 24, theedge 22 being indicated as at 25, and the edge 23 indicated, as at 26.The purpose of indicating the cutting edges of the blade will bepresently referred to. The blade is provided with a substantiallyoval-shaped opening 27 for the passage of the boss 17, the squared edgesof the latter preventing the turning or shifting of the blade whenmounted upon the boss and positioned against the inner face of theholder 16.

The reference character 28 denotes the guard, which is triangular incontour and is provided with rows of angularly depending teeth 29, eachrow associating with a cutting edge of the blade 20. The guard is formedwith a substantially oval-shaped opening 30 for the passage of the boss17, the squared edges of the latter preventing the shifting or turningof the guard 28, when the latter is mounted against the blade.

Patented Sept. 41-, 121.51.

The guard and blade are clamped to the holder, through the medium of aclamping nut 31, having a counter-bored portion 32 of greater diameter,to provide a clearance for the boss 17 when the nut 31 is screwed uponthe handle 18, to engage the guard 28, to de tachably clamp the guard,blade and holder together. The nut 31 engages with the threaded portion19 of the handle 18.

In the form shown in Fig. 2 the holder is indicated at 16, the blade at20 and the guard at 28. The boss which is formed integral with the innerface of the holder 16 includes a pair of opposed sections 50 and 17,these sections are angle-shaped in cross section and provide a seat fora head 52 integral with the outer end of the handle 18. By thisarrangement the handle is swiveled or rotatably connected to the holder.The

' no indication provided holder by revolving the handle 18 in onedirection, such action clamping the blade against the holder. When thehandle is rotated in the opposite direction, the guard will be shiftedaway from'the blade and eventually off of the screw threaded portion 19of the handle. The sectional boss prevents shifting of the blade withrespect to the holder.

Each of the blades is-furthermore provided with an indication, theindication-being a digit, as indicated at 56. It is a well known factthat when purchasing a safety razor, each of the blades are arranged ina sealed inclosure, which is torn away when it is desired to use theblade. It is also a well known fact that after the blades be come dull,they are sharpened, but there is upon the sharpened blades to indicatewhich one has been used. By providing the blades with numbers and anindicating device associating with said numbers, one can readilyascertain which sharpened blade I eating device can be upon the boxcontaining the razor and blades or it can be upon the handle.

What I claim is 2- 1. A safety razor comprising a holder, a handle,means integral with the inner face of the holder for permanentlyconnecting the handle thereto, said means permitting of, the handlerotating independently of the holder, a blade adapted to be positionedagainst the holder and means, said means preventing shifting of theblade with respect to the holder, a guard, and means integral with theguard and operatively engaging with the handle for clamping the guardand blade against said holder.

2. A safety razor comprising a holder, a handle provided with threadsand a head, means integral with the inner face of the holder andoverlapping manently connecting the head tothezhandle and for furtherpermitting of the-handle,

rotating independently of the holder, a blade surrounding said meansand..positioned against the said holder and maintained from rotatingwith respect to the holder by said means, .a guard arranged against saidblade, and the guard and engaging "ing the handle to the has been used.The indi- A rotate independently surrounding said said head for perhaving its inner face formed with tially oval-shaped boss, thecounterbore of means integral. with 'i with the threads? of the handlefor clamping the blade and guard against the holder.

3. A safety razor comprising a holder, a I handle, means projecting fromthe inner face of the holder for permanently connectholder andpermitting of the handle shifting therein, a blade surrounding saidmeans and positioned against the inner face of the holder and preventedfrom turning by said means, a guard, and means engaging with the handlefor clamping the guard and blade against the said holder.

l. A safety razor comprising a holder, a rotatable handle permanentlyconnected to the inner face thereof, a blade, a guard, and means forclamping the blade and guard against the inner holder having its innerface formed with a substantially oval-shaped boss, said blade having acorresponding orifice receiving said boss to prevent the casual turningof the blade.

5. A safety razor comprising a holder, a blade, a handle permanentlyconnected to the inner face of said holder, and allowed to of'the holderand a. means in connection therewith to clamp the blade against theinner face of the holder, said means of connection being counterboredand screw-threaded upon said handle, saidholder having its innersubstantially oval-shaped boss and said blade having a correspondingorifice receiving said.

face of said holder, said i face formed with a the blade is clampedagainstthe inner face 7 of the holder.

6. In a safety razor a holder, a handle permanently connected with theinner face thereof at right angles thereto, a blade, a guard thereforand means for clamping the elements together including a clamping nuthaving a counterbore, and screw-threaded connection with said handle,said holder said nut providing clearance for said boss.
